PROCESS FOR THE MANUFACTURE OF EASILY-EMULSIFIABLE FATTY MATTER.

Application filed August To all whom "it may concern:

Be it lrnown that I, EMIL Woimnn, a subject of the German Emperor,residing at Berlin, Germany, have invented a certain new and usefulProcess for the Manufacture of Easily-Emulsifiable Fatty Matter, ofwhich the following is a specification.

If yolks of eggs, brain matter, nerve matter, or similar products of theanimal organism, which contain phosphorus in chemical combination withorganic compounds, are subjected to extraction with organic solvents,such as alcohol, ether, chloroform, petroleum spirit or mixtures of suchsolvents, extracts are obtained, which are rich in substances containingphosphorus, such as lecithin, protagon, and also in cerebrin andcerebron. If these extracts are mixed with iodin, bromin, or mixtures ofhalogens, the halogen will readily enter into chemical combination, andwill be absorbed much more easily, than it would be by unsaturated fattyacids or fats containing the same. The extracts thus obtained andcharged with halogen are heated with fat or fatty oil, until theremainder of the solvent used has been expelled, and the fatty matterresulting from this treatment is eminently adapted for forming emulsionswith water.

The details or" procedure may be as ioll ows:-300

grams of yolks of eggs (or brain or nerve-matter, etc.)

are extracted with chloroform up to complete exhaustion, the chloroformis distilled off, so as to leave only about a liter, and the remainingchloroformic-solution is mixed with 2.5 grams of iodin and 0.2 grams ofbromin. After the product has been allowed-to stand for some time, itismixed with 10 kilogramsof arachis oil and heated while stirring, untilthe whole of the chloroform has been expelled. The oil is then allowedto cool,-filtered and thereby made ready for use. If the oil or fattymatter thus obtained is shaken with an equal volume of water, a mixtureis produced which contains the oil in a very fine state of division andis no longer liable to dissociation, that is to say, anymat-Specification of Letters Patent.

' extraction with chloroform and expelling a portion of Patented Aug.27, 1907.

pure fat, but an intimate cream-like mixture of fat with water, whichinsures an. excellent absorption of the iat and of any medicamentsincorporated with the same, by the animal organism.

An emulsion made from pure arachis oil and water is liable toseparateinto two layers, viz: a layer of pure oil and a layer of turbid water.

That the high capacity for emulsification has a favorable effect on theabsorption by the animal organism, has been proved by experiments withdogs extending over a long period. In these experiments from 98.5 to98.8 per cent of the fat taken by dogs as food was absorbed, and theutilization of the fat was therefore almost complete. The fatty matterobtained as described is therefore suitable for internal use, as asubstitute for cod-liver oil, and also for external or subcutaneous use.as a vehicle for medicaments I The great capacity for emulslfication isalso advantageous for industrial applications, for instance, if thefatty matter is intended as a lubricant for' boring tools and othermachinery.

What I.claim isz 1. The process for the production ofeasily emulsifiublfatty matter, which consists in subjecting yolks oi. eggsflti: solvent,then mixing the extract with bromin and iodin, then mixing it with fattyoil and expelling the chloroform, substantially as described.

2. The process for the production of easily emulsiflable fatty matter,which consists in subjecting yolks of 'eggs to extraction withchloroform and expelling a portion of the solvent, then mixing theextract with bromin and iodin and subsequently with arachis oil, andfinally expelling the chloroform by heat, substantially as described.

In testimony whereof I have hereunto set'my hand in presence of twosubscribing witnesses.
